Count the number of words in the string. A word is one or more non-blank characters separated by one or more blanks. My suggestion is to use a flag (a boolean variable) to indicate whether or not you are in a word. Then you know you have found a word when the flag indicates that you are in a word and the next character is a blank. Think about how you will know when you have found the end of a word, and what you should do with your flag at that point.

Sometimes writers elaborate on the truth when recalling past events so they can enhance their narrative essay with more interesting descriptions. do you feel that published writers should or should not embellish real life events just to make their stories more interesting?

Show that there is a language a ⚆ {0, 1} â— with the following properties: 1. for all x â a, |x| ≤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you don’t have to define a explicitly; just show that it has to exist. count the number of languages satisfying (1) and the number of dfas satisfying (2), and argue that there aren’t enough dfas to recognize all those languages. to count the number of languages satisfying (1), think about writing down all the strings of length at most 5, and then to define such a language, you have to make a binary decision for each string about whether to include it in the language or not. how many ways are there to make these choices? to count the number of dfas satisfying (2), consider that a dfa behaves identically even if you rename all the states, so you can assume without loss of generality that any dfa with k states has the state set {q1, q2, . . , qk}. now think about how to count how many ways there are to choose the other four parts of the dfa.
